Dating a Military Man

Thanks to all your wonderful vibes, i got the new apartment :o) I am moving TOMORROW (ah!). I have a question though:

My two roommates and i put in our 30 day notice and we are required to pay until 11/26. After i dropped off the deposit i discovered that i didn't have to move into the new apartment so soon, but i decided to just bite the bullet and do it since A) i hate that transition period when all your stuff is just sitting around in disarray B) my friend with a truck is in town for a week and would play a pivotal (if not irreplaceable) role in helping with my move C) i don't want to move close to Thanksgiving and D) i'm sort of done with my roommates.

On a whim i posted a temporary sublease ad on criagslist for my room - just for the remainder of the lease thinking i could save myself a few hundred dollars. A handful of people have inquired and one in particular wants to check out the place tonight and to move in immediately just for the month.

My question is: Should i bother to sublease? It's only for 3ish weeks and it saves me money, but a lot could go wrong (e.g. they totally trash the place, they don't want to move when the time comes, etc). Should i just eat the cost or should i take the chance and sublease?

Thanks for the advice :)
